Mr Herrmann, 20, was an aspiring rap artist and regularly posted lyrics from his songs on a Facebook page under the rap name McCodez.

Codey Herrmann, who was arrested over Aiia Maasarwe’s alleged murder, went to school just minutes from where her body was found.

On one of his Facebook pages under the name Kody Wrex, Mr Herrmann posted on January 8 this year an eerie messages which says, "international girl of mystery, you knows who you are".

As a teenage schoolboy, Mr Herrmann went missing from his school just a few blocks from the tram stop where a passer-by found Ms Maasarwe's body in bushes on Wednesday morning.

The accused only graduated from Bundoora Secondary College in 2016.

A year earlier as a schoolboy, Mr Herrmann made news after he went missing for two weeks from the college.

One of Mr Herrmann's Facebook pages links to a rap song RBGY by McCodez who sings a song with lyrics talking about "suicidal thoughts".

The song, posted on Mr Herrmann's Facebook page last October includes the lyrics, "suicidal thoughts, yeah I'll walk the line … keeping all the demons in my mind".

Other lyrics include, "no-one ever taught me how to live a normal life" and "you ain't going to mess with me".

"She loved this city and the university … very much," Mr Maasarwe said.

"I had a plan to come at the end of January … to be together with her for vacation with her sister, the older sister, to be with her for two weeks or 10 days.
